A spokesman for Great Western Railway, formerly First Great Western, said that contingency plans were in place, but wouldn’t elaborate.

He said: “Based on the number of pre-booked tickets people are prepared and we have contingency plans are in place if there are issues.

“Passengers need to make sure they check the time of their rail services beforehand.”

'We're all set'

National Express say they have laid on thousands of extra seats during the tournament.

Managing Director Tom Stables said: “We have a long history of carrying people to top sporting fixtures and we’re all set to transport thousands of fans to the Rugby World Cup 2015 on our services this month.

“It’s fitting therefore for us to be getting behind the inaugural England v Wales Legends match, which promises to be a thrilling kick-off to the world cup.

“We are adding thousands of extra seats to our services and are prepared to keep adding capacity to support as many fans as possible to get to and from the big games.”

'Fix it'

The travel concerns come after trains companies came under attack following major rail problems before the Ireland-Canada game at the Millennium Stadium on Saturday.

Welsh Secretary Stephen Crabb has called on rail companies to “Fix it” after spoke to the bosses of First Great Western and Arriva UK Trains and set out what was at stake for Wales and the Welsh capital.

It's the latest transport problem expected to affect rugby fans

First Great Western has apologised for underestimating the number of passengers who wanted to come to Cardiff that day.

There have also been warnings that passengers for today’s game between Australia and Fiji could face delays of up to three hours after the finish at the Millennium Stadium.
